Fox Demon: Heaven rewards diligence; I will eventually achieve divine mastery of martial arts.

Gradually, Kanao Tsuyuri's gaze froze.

Because Tanjiro Kamado's movements seem casual, Kanao Tsuyuri can actually see that this set of fist techniques is tight on the outside but relaxed on the inside, with strict rules and regulations. Even if a flaw is exposed, it will immediately turn into an offensive in the next set of movements.

If Kanao Tsuyuri were to face Tanjiro Kamado alone, even if their strength and speed were equal, she would very likely be defeated by the trap set by this set of punches.

What amazing boxing skills!

Kanao Tsuyuri's mind was in turmoil, because she remembered the news that had been circulating before, saying that Tanjiro Kamado had defeated Sanemi Shinazugawa, the Wind Pillar, with a punch during a meeting with a group of Pillar-level swordsmen.

I heard that Shinazugawa Sanemi was defeated with a single punch.

However, if Tanjiro Kamado had used this fist technique at that time, Kanao Tsuyuri vaguely felt that even if all the Pillar-level swordsmen present attacked together, they might not be a match for Tanjiro Kamado.

Soon, Tanjiro Kamado gradually withdrew his attacks, and Kanao Tsuyuri also calmed down.

But the next second, her eyes narrowed.

Because Tanjiro Kamado has started punching again, and while his previous punches were slow and casual, this time they are fast!

Although Tanjiro Kamado remained nonchalant, Kanao Tsuyuri actually saw a faint afterimage in the midst of Tanjiro Kamado's fist swing!

For a moment, Kanao Tsuyuri couldn't even see Tanjiro Kamado's hand movements!

Kanao Tsuyuri could only start by observing the opponent's arms. Although she couldn't see clearly at first, she soon realized that the direction and amplitude of Tanjiro Kamado's arm swings were the same as the slow punches from before!

The only difference is in the speed and release frequency.

It was precisely this difference that completely transformed Tanjiro Kamado's fighting style.

Previously upright and full of power, now it exudes a chilling killing intent, as if every punch is meant to take a life.

Boxing techniques can be done like this?

Kurihana Kanao stared blankly at the other person, and only when she noticed that the fire for brewing the medicine was getting weaker did she come back to her senses and keep the fire burning.

However, the fist technique that Tanjiro Kamado had just displayed flashed through his mind involuntarily, and the more he thought about it, the more terrifying it seemed.

But at that moment, a scream shattered the tranquility of the Demon Slayer Corps headquarters.

Then came the piercing sound of a bell, so rapid that it signified a major crisis at the Demon Slayer Corps headquarters!

Kurihana Kanao was taken aback, and her face immediately became wary.

In the past few months, the Demon Slayer Corps headquarters has recalled all the Pillar-level swordsmen, which is obviously unreasonable.

After all, the Demon Slayer Corps has a high mortality rate and is often short-handed, so the Pillar-level swordsmen are often on missions and frequently out on missions.

But when all the Pillar-level swordsmen are recalled, it means that the Demon Slayer Corps headquarters is under the most stringent security. And at this time, someone actually rings the bell that represents the highest level of alert.

At this moment, Kanao Tsuyuri could only think of one possibility: that all the Upper Moon demons had launched a full-scale attack on the Demon Slayer Corps headquarters!

She was anxious and had already gotten up, but was stopped by a voice:

"You stay here and watch the fire; you don't need to handle this matter."

Tanjiro Kamado walked in, but there was no panic on his face.

Because from the moment he told Kagaya Ubuyashiki about the plan, he already knew that this day would come.

Under Kagaya Ubuyashiki's arrangement, the entire Demon Slayer Corps headquarters became impregnable.

Furthermore, the group simulated the worst-case scenario.

All this was to protect Tamayo and Shinobu Kocho so they could focus their research on treating Nezuko.

After two months of tireless research, Tamayo and Shinobu's research has reached a critical point.

Tamayo requested the blood of a high-ranking demon, and the timing of the demon attack on the Demon Slayer Corps was perfect.

Even now, Tanjiro Kamado still marvels at the ingenuity of Lin Yu's plan.

After all, he was initially puzzled as to why having Tamayo research how to cure Nezuko required combining it with luring demons.

It wasn't until Ms. Tamayo and Shinobu's research stalled that Tanjiro Kamado finally realized what was going on.

Now, naturally, it's time to reap the rewards.

Tanjiro Kamado stepped out of the room, leaped up, and landed lightly on the roof.

With his sharp eyesight, he immediately took in the entire scene before him.

Strange scenes filled the Demon Slayer Corps headquarters at this time.

Goldfish flying in the sky were spitting poisonous stingers at the Demon Slayer Corps members patrolling around them.

An octopus the size of a house climbed onto the roof, its tentacles striking indiscriminately at anyone it saw. A single blow could easily smash through a stone wall, scattering rubble everywhere.

Fish were swimming in the sky, crashing into the Demon Slayer Corps members.

At this moment, Tanjiro Kamado noticed that all the Pillar-level swordsmen had been mobilized.

Sanemi Shinazugawa had already gripped his Nichirin Blade and slashed at the giant octopus. His blade whistled through the air, as sharp as autumn wind sweeping away fallen leaves.

Kanroji Mitsuri was wielding her specially made, retractable sword—soft like a whip yet powerful and resilient—and smashing it down on the giant octopus.

Obanai Iguro, the Serpent Pillar, lurked nearby, emanating a chilling aura.

In the distance, four monks who looked identical but had different expressions were fighting against four pillar-level swordsmen.

Tanjiro Kamado knew that it was the clone of Upper Moon Four, Hantengu.

An angry-looking monk, holding a staff, stood at the front, the staff crackling with lightning that spread outwards.

That was the most powerful of the four clones, born from accumulated anger.

With a compassionate expression, disguised as a fellow monk, Himejima Gyomei wielded a broad axe and a meteor hammer connected by a long chain. With powerful and sweeping movements, he blocked all of Hantengu's attacks, and his strong body nimbly dodged all the lightning bolts.

At the same time, he subtly suppressed his pent-up anger.

A monk with an unusually excited expression stood beside him, waving his fan around.

This clone is named Cola, and its fan can generate a strong wind powerful enough to blow a person away.

However, he had no chance to wave his fan at this moment, as he was being tightly entangled by a thin boy.

The boy was none other than Muichiro Tokito, who had been protecting Kagaya Ubuyashiki.

Tokito Muichiro's movements were like a wisp of smoke, and the traces of his Nichirin Blade were unpredictable, making it impossible for Cola to fan her fan, leaving her only able to passively defend against Tokito Muichiro's Nichirin Blade.

A monk with a sorrowful expression held a cross-shaped spear, the spear gleaming coldly in his hand.

That was Ai Jue, skilled in physical combat and marksmanship.

Facing him was Giyu Tomioka. Unlike the others who suppressed their opponents, Giyu Tomioka faced constant danger when confronting Ai Zetsu, whose spear blades always grazed his body.

However, upon closer inspection, it was discovered that Giyu Tomioka was almost unharmed; he was merely entangled with the pitiful figure before him.

In the sky, a monk with wings on his back occasionally spewed out a ultrasonic wave to attack the group of pillar-level swordsmen on the ground, relieving the pressure on his clones who were being suppressed.

That was a false alarm; the other party was very cautious and did not go down to the ground.

On the ground, Uzui Tengen, wielding twin swords, glared menacingly, seemingly searching for a weakness in Kong Xi's formation in the sky.

However, upon closer observation, it can be seen that Uzui Tengen's movements have been constantly circling around the battlefield, searching for something.

"everything is normal."

Tanjiro Kamado did not move.

Lin Yu provided the plan, and naturally also provided information on each of the Upper Moon demons.

Therefore, Kagaya Ubuyashiki had planned everything in advance, and the configuration of the people in front of him was also planned well in advance.

Yu Hu is treacherous and cunning, and his methods are unpredictable. He may not be able to be dealt with in a short time, so he has deployed three pillar-level swordsmen to prevent him from being ambushed.

Although Hantengu has many ways to protect himself, his cowardice is a huge weakness that can be quickly exploited once it is found. Therefore, four Pillar-level swordsmen were deployed to eliminate him in the shortest possible time.

"Then the question is whether there are still any demons in the Demon Slayer Corps headquarters."

Tanjiro Kamado remained vigilant in the slightest.

Since neither the first, second, nor third moons had appeared, he naturally couldn't afford to be complacent.

While the entire Demon Slayer Corps headquarters was engulfed in fierce battle, a demon arrived at the Ubuyashiki mansion.

Akaza stepped onto the ground, and several Demon Slayer Corps members fell behind him.

His face remained expressionless; he only felt that his opponents had been far too weak.

The reason for heading straight to this mansion was naturally because it was the largest and most likely housed an important person.

Before he even got close to the mansion, he noticed a figure standing quietly in front of the mansion gate.

His reddish-yellow hair burned like flames, and his expression was one of determination and confidence.

Flame Pillar - Rengoku Kyojuro.

Akaza squinted, realizing that the person in front of him was a master.

He took a step forward, unleashing an indescribable aura.

Tanjiro Kamado also noticed this, because the moment Akaza unleashed his aura, he sensed a scent similar to internal energy.

Before he could observe carefully, he sensed a faint chill emanating from the space.

He turned his head to his right and saw a figure slowly approaching the Butterfly House as if on a leisurely stroll. (End of Chapter)
